That's how a few of the first U.S. athletes to arrive at the Sochi Games feel after getting their first look at an unprecedented security presence ringing the Olympics.

With militant groups threatening to attack during the next few weeks, security for competitors and visitors to the coastal area and in the nearby mountains has become both heightened and inescapable.

Although the overwhelming forces - an estimated 100,000 police, agents and army troops - don't ensure there won't be any problems, the sheer number of security personnel has put some athletes at ease.

"I'm looking at it from the standpoint of a soldier," said U.S. bobsled member Dallas Robinson, who is also a sergeant in the Kentucky National Guard. "We're in an area where there's hundreds of thousands of people protecting us. I feel pretty safe."

Course change: The slopestyle course that drew complaints from some riders ahead of the Olympics is set to be modified after a Norwegian medal hopeful, Torstein Horgmo, broke his collarbone in practice Monday, knocking him out of the Games.
